Oil from a broken pipeline coats miles of the Pacific shoreline and endangers kelp forests at Refugio State Beach near Goleta, Calif., after a 24-inch underground pipeline broke and leaked into a culvert leading to the ocean. California's kelp forests provide habitat to sea otters, fish, sea lions and other marine life. Houston-based Plains All American Pipeline said up to 105,000 gallons of oil were released before the pipeline was shut down.
